[USER=ā4894ā][/USER] Sorry for misunderstanding, I thought you have even a little knowledge about physics side of the engine 
Also thank you for your kind reply.
@iniside Thank you for the explanation! Our project heavily depends on destruction, and Iām already worried about state of Apex in 4.22, because it became more unstable with this version. We also know that Blast is not production ready for 4.22, so I have no idea what to do in next release. I also wonder what Epic is going to show in GDC 2019: https://schedule.gdconf.com/session/causing-chaos-the-future-of-physics-and-destruction-in-unreal-engine-presented-by-epic-games/865575
